NUTRITION BY SPECIES

Feeding is never
one-size-fits-all.

Choose the animal you care for. Each guide explains the daily foundation, portions, labels, common mistakes, monitoring and appetite-related emergencies.

DOG & CAT FOOD

Choose the formula, not only the brand.

A company name can be a useful starting point, but it does not make every recipe suitable. Large manufacturers may sell grain-inclusive, grain-free, maintenance, growth and therapeutic foods under the same brand.

Reasonable places to begin

These are starting points—not blanket endorsements. Compare the exact product, life stage, nutritional-adequacy statement, formulation expertise, quality controls and your animal's medical needs.

Routine starting point

Grain-inclusive and complete & balanced

For most dogs and cats, begin with a grain-inclusive food labeled complete and balanced for the correct life stage. Grains are not a required nutrient by themselves, but there is usually no medical reason to exclude them. Use a grain-free or other restricted diet only when the veterinarian caring for the animal recommends it for a specific reason.

Not recommended

Raw and freeze-dried raw food

Freezing, freeze-drying and dehydration do not reliably sterilize raw animal ingredients. Raw diets can expose pets and people to Salmonella, Listeria and other pathogens; pets can shed organisms without looking ill. Homemade and some commercial raw diets may also be nutritionally incomplete, while raw bones can injure teeth or the digestive tract.

  • Find the AAFCO nutritional-adequacy statement and confirm the correct species and life stage.
  • Do not judge quality from the ingredient list, marketing terms or brand logo alone.
  • Ask who formulates the food, how finished products are tested and how the company handles quality problems.
  • Do not replace a prescribed therapeutic diet without speaking with the prescribing veterinarian.

For animals with disease, pregnancy, growth, weight change, dental problems or appetite loss, use these pages to prepare questions—not to design treatment without veterinary guidance.
